Determination of heating capacity for switch cabinets


P= Required heating capacity(W)

A= Complete free-standing or heat losing surface of switch cabinet (m²)

△T = Temperature difference between the ambient temperature and the average desired internal temperature of the switch cabinet(k)

k= Heat transmission coefficient Lacquered steel sheet~5.5W/m²k Polyester ~ 3.5W/m²k


When used outside: double the calculated heating capacity

■    Many various heating capacities, from 10W to 55W

■    Heating element: PTC

■    High efficiency

■    Power save and safe

■    Used pressure clamp terminal blocks in order to get wiring save time
